Description
Technical field
The present invention relates to chemical field sampler technologies, refer in particular to the side that a kind of sealing sampler and high temperature smokelessly sample
Method.
Background technology
The industries such as chemical industry need to carry out performance detection to the oil sample of different height in reaction kettle, oil storage tank in process of production.
At present, when detecting fluid product, widely used sampler is glass or metallic tube-shaped structure.Its underpart is conical pipe, middle part
For pipe, top end opening.Due to sampling process blow-by, exhaust gas volumn is big, causes serious pollution to the environment.It is (stifled) former for easily knot simultaneously
Material, cannot normally shift sample if pitch etc..
Chinese patent CN201310374988.3 discloses a kind of built-in in-situ sampling for high-temperature high-pressure reaction kettle
Device including pressure ring, thermometric pressure measurement kettle plug, sealing ring, sampling kettle plug and knob power bar, sets a sampler in autoclave body,
Sampler one end is connected by sealing cover with knob power bar, and the sampler other end is fixed on thermometric pressure measurement kettle beyond the Great Wall by pedestal,
To be threadedly coupled between sampler and sealing cover, the gap between sampler and sealing cover is equipped with sealing element, and sampler top has
Intercommunicating pore.The sampler can effectively solve the problem that in-situ sampling technology cannot reach fast simultaneously in high-temperature high-pressure reaction kettle at present
Speed, the problem of single phase and sample composition are lossless, but to be threadedly coupled between the sampler and sealing element and sealing cover, discomfort
It is used for easily tying sample, sampler needs fixed position, problematic for the sample of height change.
Chinese patent CN200920266976.8 discloses a kind of high-temperature sampler, can especially prevent oil well liquid high temperature
A kind of high-temperature sampler flashed during sampling, this high-temperature sampler is by rear head, central tube, sealant rubber ring, piston, fixed spiral shell
Silk, leading screw, front head, short circuit, elbow, feed liquor gate, go out liquid gate, handwheel composition, be characterized in that：Central tube it is front and rear
There is end socket, there is piston in central tube, piston is connected with leading screw, equipped with feed liquor gate and goes out liquid gate on front head, and when sampling beats
It is moved after driving liquid gate rotating threaded shaft piston into, liquid, which enters, closes feed liquor gate in central tube, liquid lock is opened out after liquid cooling
Door, rotating threaded shaft piston, which moves ahead, takes out qualified samples, and the sampler structure is simple, easy to operate, the effect for the sampling that can reach a high temperature,
But it uses piston to aspirate high-temp liquid, is not suitable for easily blocking up material sampling.
Chinese patent CN201310526246.8 discloses a kind of high leakproofness sampler, and delicate structure, design is rationally；
Common sampler afterbody is provided with sample tap axial annular sealing air-flow rifle, can form one layer of circular cylindrical in mineral sample tap
High pressure draught film seals sample tap；And gas end face radial direction blanket gas stream rifle is installed in common sampler Front-end Design, make to take
Sampler front port after sample forms one layer of sagittal plane high pressure draught film, sampler port is sealed so that internal sample
Gas is difficult to overflow, and avoids common sampler gas and largely loses, and ensure that the accurate of sampling, reduces measurement error, but should
Sampler is suitable for gas sample, is not suitable for high-temp liquid.
Chinese patent CN201020698357 discloses a kind of liquid sampler, by lasso, shadoof, straight-bar, sampler barrel, pressure
Lid, foundation ring, hole composition, it is characterised in that the foundation ring of hole is left under sampler barrel, leaves shadoof on sampler barrel, in sampler barrel
Gland is left, straight-bar is connected on gland, lasso is left on straight-bar, which can not achieve sealing sampling.
Yang Zhenyang etc. (insulation of electrical installation oil Full-sealed sampling device designs and application Measurement And Control of The Jet Flotation Column, and 2014, (36)：
49-51) to solve the problems, such as poor sealing present in insulation of electrical installation oil sampling process, eliminate because sampling gimmick is improper to dividing
Negative effect caused by analysing result, devises a set of insulation of electrical installation oil Full-sealed sampling device, is converted by hermetically sealed sampling
Connector, intermediate connecting leg and conversion are oriented to threeway composition, which solve leakproofness existing for former sampling mode is bad, analysis result not
The problem of accurate.The device is sampled by seal nipple using syringe.But with the height temperate zone press liquid that is taken of the present invention and easily solid
Changing sample and sampling means has larger difference.
(counter-rotating sealing sampler safeties of coal mines, 2012,43 (10) such as Chen Shaojie：94-96) from shortening sampling process
Coal sample exposure duration angle is set out, and devises a kind of counter-rotating sealing sampler, which can get clastic coal sample, and
Sampling can complete sealing to coal sample when completing, underground need not shift coal sample, directly by coal sample cylinder using quick access device into
Row underground desorbs；Compared with traditional core barrel coring, counter-rotating sealing sampling can greatly shorten the sudden and violent of coal sample in sampling process
Reveal the time, underground 30min desorption of mash gas amounts significantly increase, and reduce sampling process loss gas amount, can improve direct method survey
Determine the accuracy of coal seam gas-bearing capacity.But device, for taking solid coal sample and gas gas phase, the high temperature taken with the present invention is with pressure
Liquid is different.
